Options

A. `180^(@)`
B. `90^(@)`
C. `60^(@)`
D. `45^(@)`

Answer

b

Explanation

When a body propected at an `theta` angle it following a propacile mption At the higest point P of its piont , The vertical component of velocity because zero while horizontal component prevalls also acceleration due to gravity g always acts verticle downwards , hence angle between velocity and acceleration is `90^(@)`
